Human herpesvirus 5 Towne strain BioVector NTCC质粒载体菌种细胞基因保藏中心 Human herpesvirus 5 Towne strain
Cat#: BioVector596658
Classification Herpesviridae, Cytomegalovirus
Deposited As Cytomegalovirus
Agent Human herpesvirus 5
Strain Towne
Common Name Human cytomegalovirus
Applications Quality control
Sexually Transmitted Disease Research
Biosafety Level 2
Product Format frozen 1 mL per vial
Shipping Information Infected viable cells + 7% DMSO
Storage Conditions Liquid nitrogen vapor phase
Comments Add contents of thawed ampule to a 80-85% monolayer of HDF cells. If foci of CPE fail to spread by day 11 PI, split infected cells 1:2 and observe for CPE as monolayer reforms.
Attenuated for man, broad antigenicity. Stable for 6 months at -60°C in form of glycerinated cells. Virus primarily cell associated. A long (10-11 day) incubation is required for initial passage of frozen stocks.
Effect on Host CPE, cells round, become refractile, eventually slough off the flask
Recommended Host MRC-5
Growth Conditions Temperature: 37°C
Recommendations For Infection: Trypsinize a 2-4 day old cell culture and seed at a density of 105 cells per cm2 (2.5X106cells/T25 flask; 7.5X 105 cells per T75 flask) using the virus growth medium (VGM). To the freshly trypsinized cells inoculate using a MOI of 0.1. Immediately add additional VGM depending upon the size of the flask used (recommended medium volume for T25 is 5 to 7 mL and for T75 15 to 22.5 mL). Incubate for 24 hours at 37°C in a 5% CO2 atmosphere. Aspirate media and add fresh virus/cell growth medium to remove any traces of DMSO. Continue incubation.
Incubation: 2-7 days in a 5% CO2 air atmosphere in a stationary position until CPE is seen
Effect on Host CPE, cells round, become refractile, eventually slough off the flask
